Study summary

The primary aim of the current study is to conduct a cluster-randomized control trial to evaluate the effectiveness of a novel digital intervention in reducing anxiety and digital eye strain compared to usual care among Chinese children during the period of home confinement.

Read the detailed description

In response to the coronavirus disease 2019 (COVID-19), many countries have taken the decision of school closure after the confirmation of coronavirus cases in the general population. In China, the burden of COVID-19 is among the highest in the world, with more than 80,000 cases confirmed by 11th March 2020. An estimate of 220 million children and adolescents are confined at home for weeks with inadequate level of physical activity and more susceptible to anxiety. There is also a concern of digital eye strain for many children who spend hours daily in front of a computer screen for recreation or learning purposes.

Recess represents an essential scheduled period in a school day for psychological and physical relaxation. During the unusual period of home confinement, many schools have already issued physical activity requirement and policy recommending recess and physical activity breaks. However, recess could be easily skipped by students during online learning at home.

Mobile health intervention offers a potential opportunity for capitalizing on digital technology as a feasible modality to encourage recess activities, especially in regions where social distancing is implemented as an emergency measure. The primary aim of the current study is to conduct a cluster-randomized control trial to evaluate the effectiveness of a novel digital intervention during recess in reducing anxiety and digital eye strain compared to usual care among Chinese children during the period of home confinement.

Study arms

  • Experimental
    Digital intervention

    Participants will have access to a live-streaming App that offers Recess and Exercise Advocate Program (REAP).

    Behavioral: Digital intervention

  • Active comparator
    Information-only intervention

    Participants will have access to health information only.

    Behavioral: Information-only intervention

Interventions

  • BehavioralDigital intervention

    REAP is a live-streaming platform that allows users to shoot short videos or photos related to their physical exercise or eye relaxation (e.g., staring out of the window) using their smartphones. The app has been optimised to be used with the iPhone or Android. When taking a online course recess, students will have access to the REAP platform that allows them to watch stay-at-home workout videos developed by exercise physiologists. Students will then be asked to create their own workout videos/photos and upload them to the live-streaming platform. When upload is completed, students will receive instant motivational messages to increase their engagement with the program.

  • BehavioralInformation-only intervention

    Participants will have access to online health information and stay-at-home workout videos.

What researchers measure

Primary outcomes

  1. Change in anxiety

    Change in anxiety will be measured by the Spence Children's Anxiety Scale (SCAS) designed by Spence (1998). The SCAS (45-item) is self-report scale with a 4-point Likert type, consisting of 44 items and one open-ended question. Overall assessment is done by total score.

    Time frame: Baseline & at 2 weeks

Secondary outcomes

  1. Change in syndromes of digital eye strain

    Syndromes of digital eye strain will be measured with the Computer Vision Syndrome Questionnaire (CVS-Q) designed by Seguí et al (2015). The self-reported CVS-Q questionnaire (16-item) evaluates the frequency (never, occasionally or often/always) and the intensity (moderate or intense) of 16 symptoms: burning, itching, feeling of a foreign body, tearing, excessive blinking, eye redness, eye pain, heavy eyelids, dryness, blurred vision, double vision, difficulty focusing for near vision, increased sensitivity to light, colored halos around objects, feeling that sight is worsening, and headache. Overall assessment is done by total score.

    Time frame: Baseline & at 2 weeks

  2. Change in sleeping quality

    The PROMIS pediatric sleep disturbance questionnaire (4-item), designed by Forrest et al (2018), assesses self-reported experiences of sleep disturbance over the past 7 days. Raw score will be converted to T-Score.

    Time frame: Baseline & at 2 weeks

  3. Changes in time (hour) spent on different near work activities

    Participants will be asked to indicate the average time in hours per day spent on each the following activities: reading, writing, computer/PAD use, smart phone, watching TV, and playing video games.

    Time frame: Baseline & at 2 weeks

Ran from Mar 2020 to primary completion in Mar 2020, 0 months.

Of 3,841 non-industry interventional studies with no phase under Anxiety Disorders, half reached primary completion within 12 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 28. This study's 0 months is below that.

Counting every sponsor, half of 3,943 studies reached it within 12 months; a quarter within 5 and three quarters within 28.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 12, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
